Description

Technical Field

[0001] This utility model relates to the field of biomass pellet heating stove technology, specifically a flip-over ash removal device based on a biomass pellet heating stove. Background Technology

[0002] Biomass pellet heating stoves, as a clean heating device, have been widely used in recent years due to their advantages such as renewable fuel and low carbon emissions. Their core working principle is to generate heat by burning biomass pellets. The ash produced after combustion needs to be cleaned regularly to avoid accumulating and clogging the ventilation holes at the bottom of the furnace, which would affect the combustion efficiency.

[0003] However, traditional ash removal methods mostly rely on manual ash removal or simple lever structures, which require frequent opening and closing of the furnace door and repeated ash removal with shovels. This process is not only cumbersome and time-consuming, but also generates dust when a large amount of high-temperature ash comes into contact with cold air at the moment the furnace is turned on, causing environmental pollution and respiratory discomfort to users. Furthermore, it can cause a sudden drop in furnace temperature, requiring reheating to the set temperature after restarting, resulting in heating interruption and fuel waste.

[0004] In addition, manual ash removal is difficult to completely remove the ash residue in the dead corners at the bottom of the furnace. The residual ash residue will obstruct air circulation, resulting in insufficient mixing of fuel and oxygen during subsequent ignition, slow flame spread, significantly prolonging the ignition time and affecting the user experience. Utility Model Content

[0005] The purpose of this invention is to provide a flipping and ash-removing device based on a biomass pellet heating stove to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A flip-over ash removal device based on a biomass pellet heating stove, comprising:

[0008] L-shaped joystick;

[0009] A baffle plate, which is fixed to the upper surface of the horizontal section of the L-shaped rocker arm;

[0010] Two support blocks are rotatably connected to the outside of the horizontal section of the L-shaped rocker arm, and the two support blocks are symmetrically distributed on both sides of the baffle plate.

[0011] A rocker arm limiting mechanism is movably attached to the surface of the vertical section of the L-shaped rocker arm, which is closer to the horizontal section.

[0012] As a further embodiment of this utility model: the rocker arm limiting mechanism includes a C-shaped seat, on both the front and rear surfaces of the C-shaped seat are provided with vertical sliding holes, and on both the front and rear surfaces of the C-shaped seat below the vertical sliding holes are provided with oblique sliding holes. Support rods are fixedly connected to both the front and rear surfaces of the C-shaped seat above the vertical sliding holes. The two support rods are rotatably connected to a limiting plate. Notch 1 is provided at the lower ends of both the front and rear sides of the limiting plate, and notch 2 is provided at the left end of the limiting plate. An adjustment mechanism is provided on the inner surface of the C-shaped seat.

[0013] As a further embodiment of this utility model: the adjustment mechanism includes a T-shaped pressure plate, with waist-shaped plates fixedly connected to both the front and rear ends of the T-shaped pressure plate. A rotating rod is rotatably connected through the upper ends of the two waist-shaped plates. A tension spring is sleeved on the outside of the rotating rod between the two waist-shaped plates. A connecting rod is fixedly connected to the opposite side surfaces of the lower ends of the two waist-shaped plates.

[0014] As a further improvement of this utility model: the second notch is movably fitted to the surface of the vertical section of the L-shaped rocker arm and the side closest to the horizontal section.

[0015] As a further embodiment of this utility model: the two waist-shaped plates are respectively movably attached to the inner front and rear surfaces of the C-shaped seat, the rotating rod is slidably connected to the inside of the two vertical sliding holes, and the rotating rod is movably located inside the two notches, the upper end of the tension spring is fixed to the inner right surface of the C-shaped seat, and the connecting rod is slidably connected to the inside of the oblique sliding hole.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. Through the linkage design of the L-shaped rocker arm and the baffle plate, combined with the quick unlocking and locking function of the rocker arm limiting mechanism, the ash and slag dumping is made convenient and dust-free. During operation, simply press the T-shaped pressure plate and rotate the L-shaped rocker arm to drive the baffle plate to flip, discharging the ash and slag from the bottom of the furnace in one go, avoiding the dust problem caused by repeated operations during traditional ash removal. At the same time, after the baffle plate is reset, it is precisely engaged with the L-shaped rocker arm through the notch of the limiting plate, ensuring stable material support during combustion, shortening the ignition preparation time, and significantly improving the ash removal efficiency and safety of the heating furnace.

[0018] 2. The rocker arm limiting mechanism achieves multi-state locking of the L-shaped rocker arm through the coordinated action of the C-shaped seat, the limiting plate, and the adjusting mechanism. When the limiting plate rotates counterclockwise to the parallel state, the rocker arm automatically engages with another vertical notch one through the spring return, ensuring the temporary fixation of the limiting plate during the dust removal process. After the dust removal is completed, pressing the T-shaped pressure plate again will drive the limiting plate to rotate and reset, and the second notch will precisely lock the L-shaped rocker arm, effectively preventing accidental flipping of the baffle plate due to accidental contact or vibration. It combines operational flexibility and mechanical stability, greatly reducing the risk of equipment failure. Attached Figure Description

[0025] Please see Figures 1-5 In this embodiment of the invention, a flipping and ash-removing device for a biomass pellet heating stove includes:

[0026] L-shaped joystick 1;

[0027] L-shaped rocker arm 1 moves through the outer sidewall of biomass pellet heater 18;

[0028] baffle plate 2 is fixed to the upper surface of the horizontal section of L-shaped rocker arm 1;

[0029] The baffle plate 2 is located inside the bottom end of the furnace of the biomass pellet heating furnace 18 and is used to support the material.

[0030] Two support blocks 3 are rotatably connected to the outside of the horizontal section of the L-shaped rocker arm 1, and the two support blocks 3 are symmetrically distributed on both sides of the baffle plate 2.

[0031] The support block 3 is welded to the bottom surface of the biomass pellet heating stove 18;

[0032] The L-shaped rocker arm 1 and the support block 3 can be connected by a bearing. The outer ring of the bearing is fixed in the support block 3, and the inner ring is fixed to the outside of the L-shaped rocker arm 1, so that the L-shaped rocker arm 1 and the support block 3 are in a rotating state.

[0033] Rotating the vertical section of the L-shaped rocker arm 1 causes the baffle plate 2 to flip, which can discharge the ash and slag after combustion from the furnace, realizing the function of quickly dumping ash and slag, changing the trouble of generating a lot of dust from the traditional reciprocating ash and slag removal, and thus shortening the ignition time.

[0034] The rocker arm limiting mechanism 4 is movably attached to the surface of the vertical section of the L-shaped rocker arm 1 and the side closest to the horizontal section.

[0035] The rocker arm limiting mechanism 4 includes a C-shaped base 5. Vertical sliding holes 6 are provided on both the front and rear surfaces of the C-shaped base 5, and oblique sliding holes 7 are provided on both the front and rear surfaces of the C-shaped base 5 below the vertical sliding holes 6. Support rods 8 are fixedly connected to both the front and rear surfaces of the C-shaped base 5 above the vertical sliding holes 6. A limiting plate 9 is rotatably connected to the outside of the two support rods 8. Notch 10 is provided at the lower ends of both the front and rear sides of the limiting plate 9, and notch 21 is provided at the left end of the limiting plate 9. Notch 211 movably fits against the surface of the vertical section of the L-shaped rocker arm 1, near the horizontal section. An adjustment mechanism 12 is provided on the inner surface of the C-shaped base 5. The adjustment mechanism 12 includes a T... The front and rear ends of the T-shaped pressure plate 13 are fixed with waist plates 14. The two waist plates 14 are respectively movably attached to the front and rear sides of the interior of the C-shaped seat 5. The upper ends of the two waist plates 14 are connected to a rotating rod 15 through which the rotating rod 15 is rotatably connected. The rotating rod 15 is slidably connected to the interior of the two vertical sliding holes 6, and the rotating rod 15 is movably located inside the two notches 10. The outside of the rotating rod 15 is sleeved between the two waist plates 14. The upper end of the tension spring 16 is fixed to the right side of the interior of the C-shaped seat 5. The lower ends of the two waist plates 14 are fixed to the opposite sides of the surface of the two waist plates 14. The connecting rod 17 is slidably connected to the interior of the oblique sliding hole 7.

[0036] The C-type seat 5 can be fixed to the external side wall of the biomass pellet heater 18 by bolts or welding.

[0037] The limiting plate 9 is fitted onto the outside of the vertical section of the L-shaped rocker 1 through the notch 2 11 to limit the L-shaped rocker 1 and prevent the L-shaped rocker 1 from accidentally causing the baffle plate 2 to flip over, thus resulting in material leakage.

[0038] Looking from front to back (front view), the left end of the oblique sliding hole 7 is higher than the right end;

[0039] When the C-shaped seat 5 and the limiting plate 9 are perpendicular, the second notch 11 is fitted outside the vertical section of the L-shaped rocker 1, and the rotating rod 15 is located inside the two notches 10. Pressing the lower end of the T-shaped pressure plate 13 to the right can drive the connecting rod 17 to slide downward in the inclined sliding hole 7. At this time, the waist plate 14 rotates outside the rotating rod 15 while driving the rotating rod 15 to slide downward along the vertical sliding hole 6. The rotating rod 15 will then disengage from the inside of the first notch 10, and the limiting plate 9 can rotate counterclockwise around the support rod 8 (it can rotate to be parallel to the C-shaped seat 5). The second notch 11 will then disengage from the vertical section of the L-shaped rocker 1 and be close to the side surface of the horizontal section, allowing the operator to rotate the L-shaped rocker 1.

[0040] like Figure 2 As shown, there are two notches 10. The notch 10 mentioned above is vertically downward, while the notch 10 here is horizontally to the left. When the limiting plate 9 rotates to be parallel to the C-shaped seat 5, the notch 10 that was originally horizontally to the left rotates to be vertically downward. When the T-shaped pressure plate 13 is released, the rotating rod 15 is inserted into the notch 10 for positioning.

[0041] The working principle of this utility model is as follows: When it is necessary to remove ash from the furnace, the operator presses the lower end of the T-shaped pressure plate 13 of the rocker arm limiting mechanism 4 to the right. The connecting rod 17 moves downward in the inclined sliding hole 7, causing the rotating rod 15 to slide down along the vertical sliding hole 6, so that the rotating rod 15 disengages from the vertically downward notch 10 of the limiting plate 9. At this time, the limiting plate 9 rotates counterclockwise around the support rod 8 until it is parallel to the C-shaped seat 5. The notch 11 separates from the L-shaped rocker arm 1. After the T-shaped pressure plate 13 is released, the rotating rod 15 rebounds under the action of the tension spring 16. Ascend along the vertical sliding hole 6, engage with the limiting plate 9, and after rotation, position it in the vertically downward notch 10. Then, grasp the vertical section of the L-shaped rocker arm 1 and rotate it outward, causing the baffle plate 2 on the horizontal section to flip upward, discharging the ash from the bottom of the furnace. After cleaning, rotate the L-shaped rocker arm 1 in the opposite direction to reset the baffle plate 2 to the horizontal support position. After releasing the T-shaped pressure plate 13, press the T-shaped pressure plate 13 to rotate the C-shaped seat 5 to a horizontal state, so that the notch 11 engages with the L-shaped rocker arm 1, achieving a safe lock and completing the dust-free cleaning operation.
